IMPROVEMENT IN CQMBINED HARROWS AND SEDERS.

The Schedule'referred to in these Letters Patent and making part of thesame.

I, Enna Srosnu, of Greencastle, in the county of Improved HarrowandSeeder Combined, of which the followingT is a specification.

The lirst part 'of my invention relates to the combination ot anadjustable endless apron or band of rubber or other elastic material,with one ofitwo pulleys or rollers, under each droppiiig-aperture in thebottom ot' a seed-hopper, the apron being stretched over a thirdthereof, the objectof this part of my invention being` to' facilitatethe discharge and distribution of the seeds.

The second part of mylinventiou relates to an arran gement ofspur-gearing, consisting of three equaltoothed wheels, meshing in train,and secured respectively upon the two parallel roller-shafts under thehopper and upon the axle of the machine, under one of them for thepurpose of driving the roller-shafts and one .end to the rear bar fromwhich the harrowis in part suspended, and so pivoted to the frame-workatfrom the ground will cause the inner end of the lever to bear upon `theaxle, and to elevate the frame of the machine, and with it the toothedwheels upon its roller'- shafts, so that they will be disengaged fromtheir connection with the toothed wheel on the axle, (this upwardmovement of the frame from the axle being permitted by means of anextended vertical slot in the bearing or journal-box of thc.axle,) theobject of this part of nry'invention being to relieve the rollersandaprons of='the seeder from wear and teal-when the inachin'es not inoperation.

In the accompanying` drawing- Figure 1 isa top or plan view of myimproved ina-4 chine..

Figure 2, a rear elevation thereof.

Figure 3, au underneath lview of the bottom ofthe hopper, Sac., with allbut one oi' the seeding-rollers removed.

Figure 4, a vertical section in line y y of tig. l, giving an end Viewof the hopper, and illustrating the attachment and operation of thelever, gearing .and nngearing' the toothed wheels on the axleanrLroller-` shafts.

Figure 5,' a vertical section in line s of iig. 2, giv. ing anv,elevation of the opposite end of the seed-hopper and ofthe devices forfmoving the agitators' or stirrers within the same, and. forconncctingthe wheel with the revolving axle ofthe machine.

A is a seed-hopper of usual form and construction, supported upon aframe, B, by means of, interposed' blocks, C O, at either end.

The frame B is constructed of the side-bars li'b, connected byatransverse bar, c, in front, to the center whereof a tongue or pole, D,is secured.

E is the axle of the machine, turning freely in suitable boxes, ce',secured to the under side of the bars b li', ofzthe frame B, 'under theblocks C O, supporting the hopper.

H H are wheels ot ordinary construction, carrying the ends of the axleE.

The journal-box e', at one end of the axle, is slotted vertically, so asto permita movement' of the bar Zi', of the frame, independent oftheaxle.

F F' are arms or levers pivoted to the rear ends of the bars b b of theframe, at a point on the outer face of each, in the rear of the axle.

These levers extend outward beyond the ends of the hars b b, and areconnected by a transverse bar,

The inner end of the-lever F', pivoted to the bar b w w 'lol and centralcross-bar, the cross-bar, in common with the side-bars, heilig properlyarmed with teeth.

lhisharrow W is swung beneath the seeder A, by means of short chains, tt, (connecting its cross-bar with the rear bar G,) and an extendedpivoted link, u, connecting its front angle with the front bar c of theframe B, immediately in the rear of the tongue D.

The chains t t are so proportioned as that, when the bar G is elevatedso as to be caught by a hook, s, ou t-he hopper, the harrow will belifted entirely clearfrom the ground,;s01-as to be readily transportedfrom eld to eld. By 'dropping 'the bar G the harrow is left free todra-g upon the soil. Its transverse bar strikes in theV rear of theseed-apertures of thehopper, so that the seeds will be caught anddistributed or buried by its teeth, the rear bars beingarmed with narrowshares in addition to the ordinary points, to facilitate the latter end.

K is a spur-wheel, securedto the axle inside ofthe block O.

` L L', (see fig.4,) are-two parallel shafts, made of anni dans L',gearing in to the toothed wheel onvL, will also gear p into thespur-wheel K on the axlell. Hence, when the' harrow is dropped totakehold ofthe ground, the vsrinr-gearing is complete, and the shaftsL'L will revolve in unison with the axle, while the elevation oftheharrow by the lifting ofthe bar G will, through the movement of itsleverll", unship the .gearin g and laure the axle free-to turnindependently ofthe roller-shafts LL.

M M ate rollers, secured in pairs, one, upon each shaft, under eachdroppingLapel-ture in the bottom of the hopper, along its'entire length.

M is a pulley of equal diameter with said rollers, revolving in asuitable bracket, f f, secured to theunder side of `a plate, 0," slidingin ways upon the under side of the hopper, in the rear of each pair ofrollers.

N is an elastic band of rubber, passing over the pulley Mf and theroller 'M' nearest thereto. This band may be tightened or loosened bymeans ofthe sliding plate O, which isy secured by a set-screw, g',working through a 'slot in the plate as shown in iig. 3.

l) (see iig. 5) is'a disk, secured eccentrically on thc outer side ofthe'end of t-ho hopper A, in t'lieprojecting emLof the shaft K'.

Q (sce dotted lines, fig. 2,) is a rocking-shaft, extendinglongitudinally through the hopper, and setin motionby means of a' crank,q, upon its outer end, connected, -hy a link, i, to lthe eccentric 1.rocking-shaft Q is placed a yseries of arms or stirrers,

one over' each seeding aperture, wl1ichi'rom thero'cking rnoycmentof`the shaft, are iliade to ,swing back and forth in the hopper over saidapertures, to agitate l the Train and revent it fromclonr inw as it)asses out.

b D D lhe wheels H H may bel fastened upon the Aaxle E, or-may'beleftfree to turn thereon. In the latter case I iix aV pawl, R, upontheinner end of the hub of the' wheel, (see iig. 5,) to engage aconcentric ratchet, 7s, upon the axle, the teeth ot' the ratchet beingso in.-

Upon this clined, and the pawl so adjusted with reference thereto, asthat, when the machine is carried forward, the pawl will engage theratchet and cause the axle to revolve with the wheel butin case of areverse move ment,the wheel will turn upon the axle independentlythereof. v

The dropping-apertures in the bottom ofthe hopper slides, in the usualmanner. The employment of the horizontally-moving elastic bands N N, incombination with an opposite roller, M, under the seed-apertures,insures a more perfect andregular deliveryof the seeds than is attainedby the ordinary devices.

and shares on its transverse and rear bars bury and cover the seedsdropped in front thereof.

By properly adjusting the seed-apertures iu the bottom of the hopper,the quantity of seed 'to be sown is perfectly controlled.

Although my machine is especially adapted for sowing'brozulcast, AI,nevertheless, can readily adapt it for sowing in drills, bysecuringthereto the ordinary drilltubes in proper position under the apron undereach aperture.

I. claim as my inventionl. The combination of an elastic endless apronwith rollers and pulleys under each dropping-aperture in the hopper of aseeding-machine, said apron heilig arranged and made to operatesubstantially as andv forA the `purpose herein set forth.

2. The combination of the lever l1" with the end of the axle E and withthe frame bof a seeding-machine, substantiall y as and for the purposeherein set forth.
